A method for switching a channel in a wireless local area network is provided. A station which is a member of a basic service set (BSS) receives information on a non-primary channel access (NPCA) primary channel within a BSS bandwidth of the BSS from an associated access point (AP). The station receives an inter-BSS physical layer protocol data unit (PPDU) on a BSS primary channel and switches from the BSS primary channel to the NPCA primary channel for an NPCA operation if (i) channels occupied by the inter-BSS PPDU does not overlap with the NPCA primary channel, and (ii) the station maintains an intra-BSS network allocation vector (NAV) counter with a zero value.

One example discloses a wireless device including: a wireless transceiver configured to receive a first frame from a first wireless access point (AP) for multi-AP coordination that is not associated with the wireless device and a second frame from a second wireless AP for multi-AP coordination that is associated with the wireless device; and a controller configured to set a network allocation vector (NAV) timer of the wireless device to a non-zero value in response to the first frame and the second frame, wherein the wireless transceiver is further configured to transmit a physical protocol data unit (PPDU) to the second wireless AP even if the NAV timer of the wireless device is non-zero.

There is a method and a device arranged to perform the method. The method comprises transmitting, by a first access point (AP), to a second AP and during a transmit opportunity (TXOP) obtained by the first AP, a first frame indicating a first duration within the TXOP allocated to the second AP; receiving, by the first AP from the second AP and during the first duration, a trigger frame addressed to a first station (STA); receiving, by the first AP from the second AP and during the first duration, a second frame indicating a return of the first duration by the second AP to the first AP; and after receiving the trigger frame and the second frame, transmitting, by the first AP to the second STA, a third frame for resetting a basic network allocation vector (NAV) of the second STA.

A method for switching channels in a wireless local area network is provided. A station, as a member of a Basic Service Set (BSS), receives information from an associated access point (AP) regarding the Non-Primary Channel Access (NPCA) primary channel within the BSS bandwidth of that BSS. The station receives inter-BSS Physical Layer Protocol Data Units (PPDUs) on the BSS primary channel and switches from the BSS primary channel to the NPCA primary channel to perform NPCA operations when the following conditions are met: (i) the channel occupied by the inter-BSS PPDU does not overlap with the NPCA primary channel, and (ii) the station maintains the value of the Network Allocation Vector (NAV) counter within the BSS at zero.

This disclosure provides methods, components, devices and systems for channel access in coordinated spatial reuse. Some aspects more specifically relate to a shared access point (AP) ignoring the network allocation vectors (NAVs) indicated by transmissions from the sharing AP and the other shared APs during a shared transmission opportunity (TXOP). In some examples, the shared AP may ignore the NAVs indicated by transmissions from the sharing AP and the other shared APs during the shared TXOP in association with the control message transmitted by the sharing AP indicating that the TXOP is designated for spatial reuse also may indicate a transmit power backoff. Various aspects relate to the application of the transmit power backoff and the transmission schedule indicated by the control message for the duration of the shared TXOP by a shared AP. Various aspects relate to handling transmission by a shared AP during overlapping shared TXOPs.

Methods and apparatuses for wireless networks are provided. One method includes transmitting, by a first access point (AP), a first frame to a first station (STA) during a portion of a transmit opportunity (TXOP) shared by the second AP with the first AP, receiving, by the first AP, a second frame from the first STA in response to the first frame, based on the second frame indicating that the first STA does not have buffered data for transmission to the first AP, transmitting, by the first AP, a third frame to the first STA that triggers transmission of a first truncated frame by the first STA for resetting a first basic network allocation vector (NAV) of a second STA, and transmitting, by the first AP, a second truncated frame for resetting a second basic NAV of a third STA.
